Abstract: The current density， field intensity and charge distribution in transient dielectric barrier discharge have been investigated. The energy transfer during the discharge has also been analyzed. The results showed that both the energy from the applied high-voltage source and the energy increment of the electric field were related with the density of wall charge. However, the work done by the discharge current in the gas region is independent of the density of wall charge and the kind of current waveform.
